Appropriately titled “Switch,” the first video (above) finds Dan Stevens’ character — a diagnosed schizophrenic named David Charles Haller, the son of X-Men mastermind Charles Xavier — recalling an incident in which he accidentally switched bodies with a girl by locking lips.

Premiering in early 2017, Legion follows David’s personal journey, as he discovers that the voices and visions he’s been experiencing in his head might actually be real.
